' Specification of Letters Patent. I Pafghtd 17 1921 Application filedJ'u1y 12, 1917. Serial No. 180,122.

To all who-m it may concern:

Be it known that I, Issro H. GARsoN, a citizen of theUnited States,residin at De troit,county,of Wayne, State of Michigan, have invented acertain new and useful Improvement in Advertising Devices, and declarethe following to be a full, clear, and exact description of the same,such as will enable others skilled in the art to which it pertains tomake and use the same, reference being had to the accompanying drawings,which form a part of this specification.

This invention relates to advertising devices, and its'object is anadvertising device provided with interchangeable transparent slidesadapted to be shown one at a time. Another object of the invention is ameans for lighting one side of 'the'device at a time, and means forintermittently rotating the device. These and other objects and theseveral novel features of the invention in its preferred form arehereinafter more fully described and claimed and shown in theaccompanying drawings in which-' Figure 1 is an elevation of the device.

Fig. 2 is an enlarged vertical section of the lamp structure shown inFig. 1.

Fig. 3 is a section showing the means for holding the advertising matterin position within the lamp.

Fig. 4 is an elevation of the holder for the advertising matter.

Fig. 5 is a section therethrough.

Fig. 6 is a top view of the device with the top plate removed.

Fig. 7 is a plan viewof the mechanical means for rotating the devicewhich is in eased within the base thereof.

Fig. 8 is a section on line mm of Fig.7.

Fig. 9 is a section on line m-zv of Fig. 3.

Similar characters refer to similar parts throughout the drawings andspecification.

The device consists of a base 1 upon which is mounted a lamp structure,adapted to be rotated by mechanism contained with the base ashereinafter described. The lamp is made up of a base. part 2 and a toppart 3, fitting thereon. As will be noted from Fig. 1 the part 2 issupplied with rectangular apertures 4 which are adapted to receive aholder 5 as shown in Figs. 4 and 5. This holder 5 is adapted to containtwo panes of glass between which is a celluloid film containingadvertising matter, pictures, or other matter to be displayed. Thisholder 5 with h g ss and film therein m y e lifted by the handle; 6, andby removing the'top 3 0f the lamp." 1t may be set in the rectangularopening 4 in which place it is held in guideways, it being understoodthat there are four such rectangular openings 4 about the part 2' of thelamp. About the apertures 4 is a scroll work 7 of any desired ornamentaldesign, and by placing different coloredglasses behind the said scrollwork a pleasing result may be obtained. As will be noted moreparticularly in Figs. 2, 3 and 6, the top part of the lamp 3 is. adaptedto receive holders containing afilm between two panes of glass andhaving advertising matter thereon, and

this glass is held in place adjac'ent'the opening 8 by the spring hinge9 which holds the lower edge of the holder in place. To hold the upperedge of the holder in placeqthe device is provided with spring pressedretaming members 10 whlch are adapted to en gage the top edges of theglass and hold them in place in the top part 3. As will be noted moreparticularly from Fig. 3, the

part 2 is providedwith a flange 11 and the part 3 is provided with aflange12 which, is adapted to engageover the flange 11 and thus hold thepart 3 in proper relation to the part 2. As will be seen moreparticularly in Fig. 2 the outer tube 13 of the lamp shaft is secured tothe lamp head by set screws 14,

and thus the lamp head is rotatable with the a shaft 13. An inner tube15 is provided.

within the tube 13 upon which an incandescent lamp 16 is mounted andprovided with. :a shade 17 which throws light upon one side of the lampat a time, the tube 15 being hollow to receive the electric wires'of'theincandescent lamp 16.

The mechanisnn'for rotating the lamp "is shown more particularly inFigs. 8 and 9 which provides a driving means consisting of a motor 20mounted on thebase 1 of the lamp, the motor being provided with a shaft21 having a worm 22 on the end thereof, and the shaft 21 being providedwith a bearing 23 on the opposite end of the motor. 3

bearing rings 34L and 35 which are secured thereto by set screws. Thesebearing rings bear on the bushing 36 and are adapted'to prevent verticalmovement of the tube 13.

pins 42 are provided on the gear 27, the

cam 28 being also provided with indented portions 43. Thus it can beseen that the motor20 rotates the shaft 21 thus rotating the worm 22which in turn rotates the worm gear 2tand the worm gear 27 and the cam28, which is secured to it, though the cam 28 is'rotated very slowly.Thus it can be seen that by rotation of the cam in the direction of thearrow shown in Fig. 7 the pin 42willengage in a slot 4:1 of the cam 39and as the pin 42 moves the end 44 of the cam moves into-the indentation4:3 and is then moved out which turns the cam 39 one-fourth of a turnand allows the next face to move in contact with the face 45 of the cam28. Thus by this mechanism the lamp is turned one-fourth of a turn'andthen stopped for a suflicient time to allow the advertising thereon tobe read whereupon it is rotated another quarter of a turn and stoppedagain. Thus by use of the shade and means for rotating the lamp aquarter of a turn at a time only one side of the lamp containingadvertising matter is displayed at a time and as=the lamp has two partscontaining four sides each, eight different advertising signs may beused. By taking the holder, glass, and film out of the lamp a new filmmay be inserted thus allowing a new picture to be shown, both the top 3and bottom 2 of the lamp being adapt ed to receive new advertisingmatter. It can thus be seen that a great variety of subjects may be kepton hand for advertising and that by changing the advertising, c011-tinually difi'erent subjects are shown.

From the foregoing description it becomes evident that the device is animprovement on the well known type of advertising devices as theadvertising matter in each part of the lamp may be changed an unlimitednumber of times and thus present a new sign as often as desired.

Having thus briefly described my invention, its utility and mode ofoperation, what I claim and desire to secure by Letters Patent of theUnited States is 1. An advertising device for holding a series oftransparent films for display comprising a several sided lamp structurehaving a base part open at the top and a separable top part, each sideof the base having an opening therein and being provided with grooves oneach side of the opening interiorly of the base and in parallel relationfor supporting the film, said top part also having apertured sidescorresponding in number to the number of apertured sides of the baseproviding a cover therefor,

films, each side of the base having anopen ing therein through which afilm maybe eX- posed to view and each side of the top part havingsimilar openings therein, companion sides of the top and base beingoppositely inclined toward acommon vertical center line, said base andtop each being provided with means for supporting a film in positionrelative to the aperture, an'electric lamp held in stationary positionwithin the structure, a stationary shield adapted to project lightthrough one side only of the base and top at a time, and means forrotating the struc ture about the lamp to display the filmssuccessively.

In testimony whereof I sign this speci fication.

rssro H. GARSON.
